Fig. 1: Experiment description.
a Schematic representation of the sample. An IDT, deposited over LiNbO3, is placed 3 mm away from a set of ferromagnetic strips of different widths. The strips have an elliptical nucleation pad with the dimensions shown in the figure. The length of the strip is always 37 μm. In this figure, all the strips are 900 nm wide. b XMCD-PEEM image taken at zero external magnetic field, after the field sequence shown on top of the figure. The arrows indicate the direction of the magnetization. c XMCD-PEEM image taken after a 500 µs 25 dBm SAW pulse, always at zero external magnetic field d XMCD-PEEM image taken after a second 500 µs 25 dBm SAW pulse, also at zero external magnetic field. e–g Same sequence as (b–d) but with a Head-to-Head DW instead.
